Under settings or set-up on the remote you should be able to adjust the color of the screen images. If that does not help it may be time for a new TV.

Is the function mentioned in the manual 'optional'?

There could be two possible failures:
1. The backlights are defective (not a common failure for a 14 months old LCD) or the backlights driver/inverter is defective.
2. Power supply failure(very common failure on LCDs) will cause the symptoms you described.
